FIELD OF THE INVENTION

The present invention provides cannabinoid receptor antagonists/inverse agonists and pharmaceutical compositions thereof and methods of using the same for treating obesity, diabetes, and/or cardiometabolic disorders. The present invention also relates to a novel method for treating obesity, diabetes, and/or cardiometabolic disorders using a pyrazoline.

BACKGROUND OF THE INVENTION

Obesity is associated with an increase in the overall amount of adipose tissue (i.e., body fat), especially adipose tissue localized in the abdominal area. Obesity has reached epidemic proportions in the United States. The prevalence of obesity has steadily increased over the years among all racial and ethnic groups. The most recent data from the Centers for Disease Control and Prevention, and the National Center for Health Statistics report 66% of the adult population overweight (BMI, 25.0-29.9), 31% obese (BMI, 30-39.9), and 5% extremely obese (BMI, ≧40.0). Among children aged 6 through 19 years, 32% are reported as overweight and 17% as obese. This translates to 124 million Americans medically overweight, and 44 million of these deemed obese. Obesity is responsible for more than 300,000 deaths annually, and is one of the leading causes of preventable death in the United States. Obesity is a chronic disease that contributes directly to numerous dangerous co-morbidities, including type 2 diabetes, cardiovascular disease, inflammatory diseases, premature aging, and some forms of cancer. Type 2 diabetes, a serious and life-threatening disorder with growing prevalence in both adult and childhood populations, is currently the 7^(th) leading cause of death in the United States. Since more than 80% of patients with type 2 diabetes are overweight, obesity is the greatest risk factor for developing type 2 diabetes. Increasing clinical evidence indicates that the best way to control type 2 diabetes is to reduce weight.

The most popular over-the counter drugs for the treatment of obesity, phenylpropanolamine and ephedrine, and the most popular prescription drug, fenfluramine, were removed from the marketplace as a result of safety concerns. Drugs currently approved for the long-term treatment of obesity fall into two categories: (a) CNS appetite suppressants such as sibutramine and (b) gut lipase inhibitors such as orlistat. CNS appetite suppressants reduce eating behavior through activation of the ‘satiety center’ in the brain and/or by inhibition of the ‘hunger center’ in the brain. Gut lipase inhibitors reduce the absorption of dietary fat from the gastrointestinal (GI) tract. Although sibutramine and orlistat work through very different mechanisms, they share in common the same overall goal of reducing body weight secondary to reducing the amount of calories that reach the systemic circulation. Unfortunately, these indirect therapies produce only a modest initial weight loss (approximately 5% compared to placebo) that is usually not maintained. After one or two years of treatment, most patients return to or exceed their starting weight. In addition, most approved anti-obesity therapeutics produce undesirable and often dangerous side effects that can complicate treatment and interfere with a patient's quality of life.

The lack of therapeutic effectiveness, coupled with the spiraling obesity epidemic, positions the ‘treatment of obesity’ as one of the largest and most urgent unmet medical needs. There is, therefore, a real and continuing need for the development of improved medications that treat or prevent obesity.

The endocanabinoid system, comprised of the canabinoid receptors (CB1 and CB2) and their endogenous ligands (e.g., anandamide, 2-AG), plays a prominent role in the control of food intake and energy metabolism. CB1 receptors are widely expressed in the brain, including cortex, hippocampus, amygdala, pituitary and hypothalamus. CB1 receptors have also been identified in numerous peripheral organs and tissues, including thyroid gland, adrenal gland, reproductive organs, adipose tissue, liver, muscle, and gastrointestinal tract. CB2 receptors are localized almost exclusively in immune and blood cells, see Endocrine Reviews 2006, 27, 73.

The plant-derived cannabinoid agonist Δ⁹-tetrahydrocannabinol (Δ⁹-THC), the main psychoactive component of marijuana, binds to both CB1 and CB2 receptors. Δ⁹-THC is widely reported to increase appetite and food intake (hyperphagia) in humans and in animals. This hyperphagic effect is largely blocked by pretreatment with selective CB1 receptor antagonists/inverse agonists [e.g., rimonabant (SR141716A, Acomplia®)], strongly supporting the belief that CB1 receptor activation mediates the hyperphagic effect of Δ⁹-THC, see Endocrine Reviews 2006, 27, 73.

In humans, rimonabant produces a clinically meaningful weight loss in obese patients. Patients also experience improvements in diabetes and in associated cardiometabolic risk factors, including a decrease in triglyceride levels. Rimonabant also produces greater reductions in abdominal fat deposits, which are a known risk factor for diabetes and heart disease. Taken together, these improvements in adiposity, diabetes, and cardiometabolic risk factors produce an overall decrease in the prevalence of the metabolic syndrome, see Lancet 2005, 365, 1389-97 and NEJM 2005, 353, 2121.

The beneficial effects of rimonabant on diabetes and cardiometabolic risk factors such as high blood pressure and elevated levels of triglycerides cannot be explained by diet and weight loss alone. For example, in patients receiving 20 mg of rimonabant, only approximately 50% of the beneficial effects on triglycerides, fasting insulin, and insulin resistance can be accounted for by weight loss. These results suggest a direct pharmacological effect of CB1 antagonists/inverse agonists on glucose and lipid metabolism, in addition to indirect effects on metabolism secondary to hypophagia-mediated weight loss, see Science 2006, 311, 323 and JAMA 2006, 311, 323.

The CB1 receptor is one of the most abundant and widely distributed G protein-coupled receptors in the mammalian brain. It is believed that the appetite-suppressant properties of CB1 antagonists/inverse agonists are mediated through an interaction with CB1 receptors in the hypothalamus (regulation of food intake), and in the mesolimbic region (rewarding properties of food). However, CB1 receptors are far more broadly distributed in brain (e.g., neocortex, hippocampus, thalamus, cerebellum, and pituitary), and while interacting with targeted CB1 receptors in hypothalamus and mesolimbic regions, CB1 antagonists have ready access to non-targeted CB1 receptors that have little if any role in appetite control. Binding to non-targeted receptors can often lead to unwanted side effects of CNS drugs [Endocrine Reviews 2006, 27: 73]. The CB1 antagonist/inverse agonist rimonabant produces psychiatric and nervous system side effects. These include depressed mood, anxiety, irritability, insomnia, dizziness, and headache. These side effects are dose-related and are most pronounced at the most efficacious weight-reducing dose of rimonabant (JAMA 2006, 311, 323). The occurrence of therapeutic efficacy (appetite suppression) and side effects over the same dose range strongly suggest that both effects are mediated through concurrent antagonism of CB1 receptors in both ‘targeted’ and ‘non-targeted’ brain regions. Brain-penetrant CB1 antagonists do not selectively target CB1 receptors in efficacy brain regions, while ignoring CB1 receptors in side effect brain regions.

The beneficial effects of the CB1 antagonist/inverse agonist rimonabant on body weight, adiposity, diabetes, and cardiometabolic risk factors such as high blood pressure and elevated levels of triglycerides cannot be explained by weight loss derived from CNS-mediated appetite suppression alone, see JAMA 2006, 311, 323. Approximately 50% of the non-CNS benefit is likely derived from an interaction with CB1 receptors in peripheral tissues known to play an active role in metabolism. These include adipose tissue, liver, muscle, and gastrointestinal tract.

In view of the above, it is highly desirable to find effective and highly selective CB1 receptor antagonists/inverse agonists with limited or no CNS adverse side effects, including mood disorders. Particularly, it is desirable to find compounds that preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, and gastrointestinal tract), while sparing CB1 receptors in brain. In this way, peripherally-mediated beneficial effects of CB1 antagonists/invers agonists should be maintained, whereas CNS side effects should be reduced or eliminated. This should provide a novel opportunity to develop safer agents for the prevention or treatment of obesity, diabetes, and cardiometabolic diseases (e.g., hypertension and dyslipidemias).

SUMMARY OF THE INVENTION

Accordingly, in an aspect, the present invention provides novel pyrazolines or pharmaceutically acceptable salts thereof that are CB1 receptor antagonists.

In another aspect, the present invention provides novel pharmaceutical compositions, comprising: a pharmaceutically acceptable carrier and a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt form thereof.

In another aspect, the present invention provides novel methods for treating obesity, diabetes, and/or cardiometabolic disorders (e.g., hypertension and dyslipidemias), comprising: administering to a patient in need thereof a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt form thereof.

In another aspect, the present invention provides processes for preparing novel compounds.

In another aspect, the present invention provides novel compounds or pharmaceutically acceptable salts for use in therapy.

In another aspect, the present invention provides the use of novel compounds for the manufacture of a medicament for the treatment of obesity, diabetes, and/or cardiometabolic disorders.

These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that the presently claimed compounds or pharmaceutically acceptable salt forms thereof are expected to be effective CB1 receptor antagonists.

DETAILED DESCRIPTION OF THE INVENTION

All references cited herein are hereby incorporated in their entirety herein by reference.

The present invention is based on the finding that a CB1 receptor antagonist has beneficial effects on body weight, adiposity, diabetes, and cardiometabolic risk factors such as hypertension and dyslipidemias that cannot be explained by weight loss derived from CNS-mediated appetite suppression alone and that this effect is mediated, at least in part, through interaction at peripheral receptors. To this end, the present invention provides compounds that are designed to preferentially target CB1 receptors in peripheral tissues (e.g., adipose tissue, liver, muscle, and gastrointestinal tract), while sparing CB1 receptors in brain. Peripherally-mediated beneficial effects of CB1 antagonists should be maintained, whereas CNS side effects should be reduced or eliminated.

The compounds of the present invention have been designed to have reduced CNS exposure by virtue of their inability or limited ability to penetrate the blood-brain barrier (BBB) or by their participation in active transport systems, thus reducing centrally mediated side-effects, a potential problem with many anti-obesity and anti-diabetic agents. It is expected that the peripherally restricted compounds of the present invention will have no or very limited CNS effects. Thus, their peripherally mediated CB1 antagonistic properties should provide therapeutic agents with greater safety, as previously demonstrated in earlier classes of peripherally restricted agents.

Moreover, if the maximum dosage of a drug used in the treatment of obesity, diabetes, and/or cardiometabolic disorders (e.g., hypertension and dyslipidemias) is limited as a result of CNS side effects (e.g., seizures, depression, anxiety, movement disorders, and hyperactivity), incorporation of a peripherally restricting group in such a drug would lower the brain concentration of the drug relative to the concentration in the systemic circulation, thereby affording the opportunity to increase the dosage employed to treat the peripheral disorder. The increased dosage may provide greater therapeutic efficacy, as well as a more rapid onset of therapeutic action.

“Pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 1,2-ethanedisulfonic, 2-acetoxybenzoic, 2-hydroxyethanesulfonic, acetic, ascorbic, benzenesulfonic, benzoic, bicarbonic, carbonic, citric, edetic, ethane disulfonic, ethane sulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, glycollyarsanilic, hexylresorcinic, hydrabamic, hydrobromic, hydrochloric, hydroiodide, hydroxymaleic, hydroxynaphthoic, isethionic, lactic, lactobionic, lauryl sulfonic, maleic, malic, mandelic, methanesulfonic, napsylic, nitric, oxalic, pamoic, pantothenic, phenylacetic, phosphoric, polygalacturonic, propionic, salicyclic, stearic, subacetic, succinic, sulfamic, sulfanilic, sulfuric, tannic, tartaric, and toluenesulfonic.

The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound that contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are useful. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing Company, Easton, Pa., 1990, p 1445, the disclosure of which is hereby incorporated by reference.

“Therapeutically effective amount” includes an amount of a compound of the present invention that is effective when administered alone or in combination to treat obesity or another indication listed herein. “Therapeutically effective amount” also includes an amount of the combination of compounds claimed that is effective to treat the desired indication. The combination of compounds can be a synergistic combination. Synergy, as described, for example, by Chou and Talalay, Adv. Enzyme Regul. 1984, 22:27-55, occurs when the effect of the compounds when administered in combination is greater than the additive effect of the compounds when administered alone as a single agent. In general, a synergistic effect is most clearly demonstrated at sub-optimal concentrations of the compounds. Synergy can be in terms of lower cytotoxicity, increased effect, or some other beneficial effect of the combination compared with the individual components.

Obesity is defined as having a body mass index (BMI) of 30 or above. The index is a measure of an individual's body weight relative to height. BMI is calculated by dividing body weight (in kilograms) by height (in meters) squared. Normal and healthy body weight is defined as having a BMI between 20 and 24.9. Overweight is defined as having a BMI≧25. Obesity has reached epidemic proportions in the U.S., with 44 million obese Americans, and an additional eighty million deemed medically overweight.

Obesity is a disease characterized as a condition resulting from the excess accumulation of adipose tissue, especially adipose tissue localized in the abdominal area. It is desirable to treat overweight or obese patients by reducing their amount of adipose tissue, and thereby reducing their overall body weight to within the normal range for their sex and height. In this way, their risk for co-morbidities such as diabetes and cardiovascular disease will be reduced. It is also desirable to prevent normal weight individuals from accumulating additional, excess adipose tissue, effectively maintaining their body weights at a BMI<25, and preventing the development of co-morbidities. It is also desirable to control obesity, effectively preventing overweight and obese individuals from accumulating additional, excess adipose tissue, reducing the risk of further exacerbating their co-morbidities.

Cannabinoid receptors are located in a number of peripheral (non-CNS) tissues, including thyroid gland, adrenal gland, reproductive organs, adipose tissue, liver, muscle, and gastrointestinal tract. Cannabinoid receptor antagonists/invers agonists being developed to treat obesity and smoking cessation, regardless of route of administration, enter the CNS from the systemic circulation. While present in the systemic circulation, such drugs have access to peripheral tissues. One of skill in the art recognizes that cannabinoid receptor antagonists intended to enter the CNS from the systemic circulation in order to treat obesity and smoking cessation, also have access to cannabinoid receptors in peripheral tissues. Thus, a cannabinoid receptor antagonist useful for the present invention may have some access to the CNS from the systemic circulation.

Drugs enter the CNS from the systemic circulation by crossing the blood-brain barrier (BBB). The BBB is a highly specialized ‘gate-keeper’ that protects the brain by preventing the entry of many potentially harmful substances into the CNS from the systemic circulation. Much is known about the BBB, and of the physical-chemical properties required for compounds transported across it.

Drugs that do not cross the BBB into the CNS or that are readily eliminated through transport mechanisms (J Clin Invest. 97, 2517 (1996)) are known in the literature and have low CNS activity due to their inability to develop brain levels necessary for pharmacological action. The BBB has at least one mechanism to remove drugs prior to their accumulation in the CNS. P-Glycoproteins (P-gp) localized in plasma membrane of the BBB can influence the brain penetration and pharmacological activity of many drugs through translocation across membranes. The lack of accumulation into the brain by some drugs can be explained by their active removal from the brain by P-gp residing in the BBB. For example, the typical opioid drug loperamide, clinically used as an antidiarrheal, is actively removed from the brain by P-gp, thus explaining its lack of opiate-like CNS effects. Another example is domperidone, a dopamine receptor blocker that participates in the P-gp transport (J Clin Invest. 97, 2517 (1996)). Whereas dopamine receptor blockers that cross the BBB can be used to treat schizophrenia, the readily-eliminated domperidone can be used to prevent emesis, without the likelihood of producing adverse CNS effects.

In addition to the above compounds, agents possessing structural characteristics that retard or prevent BBB penetration or contribute to participation in active elimination processes have been identified in various classes of therapeutics. These include antihistamines (Drug Metab. Dispos. 31, 312 (2003)), beta-adrenergic receptor antagonists (B-blockers)(Eur. J. Clin. Pharmacol. 28, Suppl: 21-3 (1985); Br. J. Clin. Pharmacol, 11 (6), 549-553 (1981)), non-nucleoside reverse transcriptase inhibitors (NNRTIs)(J. Pharm Sci., 88(10) 950-954 (1999)), and opioid antagonists. This latter group has been tested in relation to their activity in the GI tract. These peripherally selective opioid antagonists are described in various US patents as being useful in the treatment of non-CNS pathologies in mammals, in particular those of the GI tract (see U.S. Pat. No. 5,260,542; U.S. Pat. No. 5,434,171; U.S. Pat. No. 5,159,081; and U.S. Pat. No. 5,270,238).

Other types of non-brain penetrant compounds can be prepared through the creation of a charge within the molecule. Thus, the addition of a methyl group to the tertiary amine functionality of the drugs scopolamine or atropine, unlike the parent molecules, prevents their passage across the BBB through the presence of a positive charge. However, the new molecules (methyl-scopolamine and methyl-atropine) retain their full anticholinergic pharmacological properties. As such, these drugs can also be used to treat peripheral diseases, without the concern of adverse CNS effects. The quaternary ammonium compound methylnaltrexone is also used for the prevention and/or treatment of opioid and non-opioid induced side effects associated with opioid administration.

The discovery that the anti-obesity and anti-diabetic activity of cannabinoid receptor antagonists may in part be mediated by a non-CNS mechanism could make it beneficial for the compounds of the present invention to be peripherally restricted, i.e., have an inability or limited ability to cross the BBB, or be readily eliminated from the brain through active transport systems. It may be desirable for the compounds of the present invention to be peripherally restricted, which in turn will result in no or very limited CNS effects. Compounds that provide peripherally mediated anti-obesity properties should result in therapeutic agents with greater safety, as previously demonstrated in earlier classes of peripherally restricted agents. It can be desirable that the compounds of the present invention, when administered in a therapeutically effective amount, have no or very limited CNS effects. It can also be desirable that the lack of CNS effects is a result of the compounds of the present invention having minimal brain concentrations when administered in therapeutically effective amounts. In this context, minimal brain concentrations means levels that are too low to be therapeutically effective for the treatment of a CNS indication or too low to cause significant or measurable deleterious or undesired side effects.

SLV319 (Compound I when X and X″ are 4-Cl; X′, Y, Y′, Y″, and Z are H; Q is CH₃; and M is SO₂) is a drug that crosses the BBB and is indicated for the treatment of obesity. It is believed that SLV319 works to treat obesity via a CNS mechanism. Compounds like SLV319 and compound AA have been described in various publications including J. Med. Chem. 2004, 47(3), 627 and U.S. Pat. No. 6,476,060. In compound AA, one of X, Y, X′, Y′, X″, Y, Z or Q is a group capable of reducing or limiting the CNS activity of compound AA. This reduced or limited CNS activity occurs via at least one of X, Y, X′, Y′, X″, Y, Z and Q being a group that either limits compound AA's ability to cross the BBB relative to that of SLV319 or enables it to be actively removed from the brain at a rate greater than that of SLV319. Examples of the amount of compound AA present in the brain can include (a) from 50, 55, 60, 65, 70, 75, 80, 85, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than SLV319, (b) from 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, to 100% lower than SLV319, and (c) from 98, 99, to 100% lower than SLV319, when administered at the same dosage.

The compounds of the present invention are expected to be cannabinoid receptor antagonists or inverse agonists.

An inverse agonist is a compound that not only blocks the action of the endogenous agonist at the receptor, but also exhibits its own activity, which is usually the opposite of that shown by the agonist. Inverse agonists are also effective against certain types of receptors (e.g., certain histamine receptors/GABA receptors), which have intrinsic activity without the interaction of a ligand upon them (also referred to as ‘constitutive activity’).

Most methods of treating obesity are dependent on a significant reduction in energy intake, either by a decrease in food intake (e.g., sibutramine) or by inhibition of fat absorption (e.g., orlistat). In the present invention, it can be desirable for adipose tissue to be significantly reduced in the absence of a significant reduction in food intake. The weight loss, as a result of the present invention, comes from the treatment with a CB1 antagonist, largely independent of appetite and food intake. Examples of the level of food intake during adipose tissue loss include (a) food intake is maintained, increased or about 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level); (b) food intake is maintained, increased, or about 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below its pre-administration level; (c) food intake is maintained, increased or about 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below its pre-administration level; and (d) food intake level is maintained, increased or about 0, 1, 2, 3, 4, or 5% below its pre-administration level.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of lean muscle mass. This is particularly evident in cancer patients who show a wasting of all body tissue components, including adipose tissue and lean muscle mass. In the present invention, however, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in lean body mass. Adipose tissue loss comes from treatment with a CB1 antagonist, independent of a significant change in lean body mass. Examples of the level of lean body mass during adipose tissue loss include (a) lean body mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level); (b) lean body mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels; (c) lean body mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels; and (d) lean body mass is maintained, increased, or is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

In some cases, loss of adipose tissue can be accompanied by a concomitant loss of water mass. This is particularly evident with diet regimens that promote dehydration. In the present invention, it can be desirable for body fat to be significantly reduced in the absence of a significant reduction in water mass. In other words, adipose tissue loss comes from treatment with a CB1 antagonist, independent of a significant change in water mass. Examples of the level of water mass during adipose tissue loss include (a) water mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, or 30% below the normal range of the subject prior to being treated in accordance with the present invention (i.e., its pre-administration level); (b) water mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15% below pre-administration levels; (c) water mass is maintained, increased, or is no more than about 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10% below pre-administration levels; and (d) water mass is maintained, increased, or is no more than about 1, 2, 3, 4, or 5% below pre-administration levels.

Sibutramine and orlistat are currently marketed for use in the treatment of obesity. These two compounds achieve weight loss through entirely different mechanisms. Sibutramine, a CNS appetite suppressant, inhibits the neuronal reuptake of serotonin and noradrenaline. Orlistat inhibits gut lipase enzymes that are responsible for breaking down ingested fat.

Cannabinoid receptor antagonists/inverse agonists can promote weight loss through inhibition of peripheral cannabinoid receptors, as well as mechanisms entirely different from appetite suppressants, gut lipase inhibitors, and other agents with similar indications (e.g., serotonin agonists, leptin, fatty acid synthase inhibitors, monoamine oxidase (MAO) inhibitors). Co-administration of a cannabinoid receptor antagonist/inverse agonist together with one or more other agents that are useful for treating the indications described above (e.g., obesity, diabetes, cardiometabolic disorders, and a combination thereof) is expected to be beneficial, by producing, for example, either additive or synergistic effects. Examples of additional agents include an appetite suppressant, a lipase inhibitor, and a MAO inhibitor (e.g., MAO-B, and a combination of MAO-A/B). Therefore, the present invention provides a method of treating obesity, diabetes, and/or cardiometabolic disorders, comprising administering a therapeutically effective amount of a compound of the present invention and a second component effective for treating the desired indication.

The compounds of the present invention are expected to be CB1 receptor inhibitors/inverse agonists and are expected to be useful for treating diseases mediated by the CB₁ receptor. The compounds of the present are expected to possess an affinity in vitro for the central and/or peripheral cannabinoid receptors under the experimental conditions described by Devane et al., Molecular Pharmacology, 1988, 34, 605-613. The compounds according to the invention are also expected to possess an affinity for the cannabinoid receptors present on preparations of electrically stimulated isolated organs. These tests can be performed on guinea-pig ileum and on mouse vas deferens according to Roselt et al., Acta Physiologica Scandinavia 1975, 94, 142-144, and according to Nicolau et al., Arch. Int. Pharmacodyn, 1978, 236, 131-136.

CB1 receptor affinities can be determined using membrane preparations of Chinese hamster ovary (CHO) cells in which the human cannabinoid CB1 receptor is stably transfected (Biochem J. 1991, 279, 129-134) in conjunction with [3H]CP-55,940 as radioligand. After incubation of a freshly prepared cell membrane preparation with the [3H]-radioligand, with or without addition of test compound, separation of bound and free ligand is performed by filtration over glass fiber filters. Radioactivity on the filter is measured by liquid scintillation counting. The IC₅₀ values can be determined from at least three independent measurements.

In the present invention, the compound(s) of the present invention can be administered in any convenient manner (e.g., enterally or parenterally). Examples of methods of administration include orally and transdermally. One skilled in this art is aware that the routes of administering the compounds of the present invention may vary significantly. In addition to other oral administrations, sustained release compositions may be favored. Other acceptable routes may include injections (e.g., intravenous, intramuscular, subcutaneous, and intraperitoneal); subdermal implants; and, buccal, sublingual, topical, rectal, vaginal, and intranasal administrations. Bioerodible, non-bioerodible, biodegradable, and non-biodegradable systems of administration may also be used. Examples of oral formulations include tablets, coated tablets, hard and soft gelatin capsules, solutions, emulsions, and suspensions.

If a solid composition in the form of tablets is prepared, the main active ingredient can be mixed with a pharmaceutical vehicle, examples of which include silica, starch, lactose, magnesium stearate, and talc. The tablets can be coated with sucrose or another appropriate substance or they can be treated so as to have a sustained or delayed activity and so as to release a predetermined amount of active ingredient continuously. Gelatin capsules can be obtained by mixing the active ingredient with a diluent and incorporating the resulting mixture into soft or hard gelatin capsules. A syrup or elixir can contain the active ingredient in conjunction with a sweetener, which is preferably calorie-free, an antiseptic (e.g., methylparaben and/or propylparaben), a flavoring, and an appropriate color. Water-dispersible powders or granules can contain the active ingredient mixed with dispersants or wetting agents or with suspending agents such as polyvinylpyrrolidone, as well as with sweeteners or taste correctors. Rectal administration can be effected using suppositories, which are prepared with binders melting at the rectal temperature (e.g., cocoa butter and/or polyethylene glycols). Parenteral administration can be effected using aqueous suspensions, isotonic saline solutions, or injectable sterile solutions, which contain pharmacologically compatible dispersants and/or wetting agents (e.g., propylene glycol and/or polyethylene glycol). The active ingredient can also be formulated as microcapsules or microspheres, optionally with one or more carriers or additives. The active ingredient can also be presented in the form of a complex with a cyclodextrin, for example α-, β-, or γ-cyclodextrin, 2-hydroxypropyl-β-cyclodextrin, and/or methyl-β-cyclodextrin.

The dose of the compound of the present invention administered daily will vary on an individual basis and to some extent may be determined by the severity of the disease being treated (e.g., obesity, diabetes, and cardiometabolic disorders). The dose of the compound of the present invention will also vary depending on the compound administered. Examples of dosages of compounds of the present invention include from about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 76, 80, 85, 90, 95, to 100 mg/kg of mammal body weight. The compound can be administered in a single dose or in a number of smaller doses over a period of time. The length of time during which the compound is administered varies on an individual basis, and can continue until the desired results are achieved (i.e., reduction of body fat, prevention of a gain in body fat, reduced glucose levels, improved insulin sensitivity). Therapy could, therefore, last from 1 day to weeks, months, or even years depending upon the subject being treated, the desired results, and how quickly the subject responds to treatment in accordance with the present invention.

SYNTHESIS

The compounds of the present invention can be prepared in a number of ways known to one skilled in the art of organic synthesis (e.g., see U.S. Pat. No. 6,476,060 B2, J Med Chem 2004, 47, 627). The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or by variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformations being effected. It will be understood by those skilled in the art of organic synthesis that the functionality present on the molecule should be consistent with the transformations proposed. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene and Wuts (Protective Groups In Organic Synthesis, Wiley and Sons, 1991). All references cited herein are hereby incorporated in their entirety herein by reference.

Scheme 1 shows how to convert 2′-, 3′-, or 4′-(carbo-t-butoxymethoxy)-2-phenylacetophenones, prepared from commercially available 2′-, 3′- or 4′-methoxy-2-phenylacetophenones via O-demethylation using HBr/HOAc or BBr₃/CH₂Cl₂ and alkylation of the resultant phenol with t-butyl bromoacetate in the presence of base, in 37% aqueous formaldehyde containing piperidine under reflux to the corresponding acrylophenones (step a). Treatment of the acrylophenones with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with arylsulfonyldithioimidocarbonic acid methyl esters, prepared from the corresponding aryl sulfonamides, CS₂ and MeI (see J. Med. Chem., 47, 627 (2004); Chem. Ber. 1966, 99, 2885), in a solvent (e.g., acetonitrile) in the presence of triethylamine at reflux to yield the pyrazole-1-carboximidothioic acid methyl ester (step c). Further exposure of these iminothioethers to an aqueous solution of methylamine and methylene chloride at room temperature should afford the pyrazoline-1-carboxamidines (step d). Hydrolysis of the ester using TFA/CH₂Cl₂ should produce the carboxylic acid (step e).

Scheme 2 describes how 2-(2′-, 3′- or 4′-carbo-t-butoxymethoxyphenyl)acetophenones (prepared similarly to scheme 1) should provide the corresponding acrylophenones (step a). Treatment of the acrylophenones with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with arylsulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux to yield pyrazole-1-carboximidothioic acid methyl esters (step c). Further exposure of these iminothioethers to an aqueous solution of methylamine and methylene chloride at room temperature should afford the pyrazoline-1-carboxamidines (step d). Hydrolysis of the ester using TFA/CH₂Cl₂ should produce the carboxylic acid (step e).

Scheme 3 shows the conversion of 4′-chloro-2-phenylacetophenone in 37% aqueous formalin and MeOH containing piperidine and acetic acid at reflux that should occur affording the acrylophenone (J. Agric. Food Chem. 1979, 27(2), 406)(step a). Treatment of the acrylophenone with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with arylsulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux to yield the pyrazole-1-carboximidothioic acid methyl ester (step c). Further exposure of these iminothioethers to beta-alanine t-butyl ester in ethanol and methylene chloride containing triethylamine should yield the pyrazoline-esters (step d). Hydrolysis of the ester using TFA/CH₂Cl₂ should produce the carboxylic acid (step e). Treatment of the ester with anhydrous ammonia in methanol at about 0° to room emperature can afford the carboxamido compound (step f). Alternatively, the iminothioethers can be coupled with other amino acid esters to give adducts (step g) that can be hydrolyzed to the carboxylic acids (step h). These acids may be converted to the carboxamides using oxalyl chloride in dichloroethane followed by anhydrous ammonia, or Boc₂O in pyridine/THF followed by anhydrous ammonia (step i).

Scheme 4 illustrates how oxidation of 4′-chloro-2-phenylacrylophenone in methylene chloride with m-chloroperbenzoic acid should provide the epoxide (step a), which upon treatment with hydrazine hydrate in ethanol solution at about 35-40° C. can give the 3,4-diarylpyrazoline alcohol (step b). The pyrazoline can be protected using di-t-butyl-dicarbonate (t-Boc anhydride) in the presence of a base to give the N-t-BOC-pyrazoline (step c). The carbamate alcohol can then be deprotonated with sodium hydride in a solvent like DMF followed by alkylation with ethyl 4-bromocrotonate to yield the ester (step d). Removal of the t-BOC group can be achieved via treatment with TFA (step e). The pyrazoline can then be reacted with arylsulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux to yield the pyrazole-1-carboximidothioic acid methyl ether (step f). Further exposure of these iminothioethers to an aqueous solution of methylamine and methylene chloride at room temperature can afford the pyrazoline-1-carboxamidines (step g), and hydrolysis of the ester using LiOH in aqueous THF solution can produce the carboxylic acid (step h). The carbxoamides can be prepared by treatment of the ester with anhydrous ammonia in alcohol at −20° C. to ambient temperature (step i).

Scheme 5 shows how heating a solution of the 3,4-diarylpyrazoline and S-methylisothiourea in pyridine can form the pyrazoline-1-carboxamidine (step a). Treatment of this amidine with t4-cyanobenzenesulfonyl chloride in acetonitrile in the presence of N.N-dimethyl-4-aminopyridine and triethylamine can give the carboxamidine-coupled sulfonamide derivative (step b). Conversion of the nitrile to the phenylcarboxamidine can be accomplished using HCl (gas) in MeOH at 0° C. to room temperature, followed by ammonium carbonate or anhydrous ammonia in MeOH at about 0° C. to room temperature (step c).

Scheme 6 describes how the reaction of a freshly prepared anhydrous acetonitrile solution of 4-chlorobenzoylisothiocyanate, made from 4-chlorobenzoylchloride and ammonium isocyanate (see J Heterocycl. Chem. 1991, 28, 1645), and a 3,4-diarylpyrazoline stirred in the cold can afford the pyrazoline-adduct (step a). Treatment of this thiocarboxamide with amino compounds such as ethyl beta-alanine in the presence of HgCl₂ can produce the benzoyl guanidines (step b). Hydrolysis of the ester using LiOH in aqueous THF solution can produce the carboxylic acid (step c). Further conversion of the acid to the acid chloride followed by treatment with anhydrous ammonia should afford the carboxamide (step d).

Scheme 7 depicts how condensation of a solution of 4′-nitro-2-phenylacetophenone in 37% aqueous formalin and MeOH containing piperidine and acetic acid should afford after heating at reflux, the corresponding acrylophenone (step a). Treatment of the acrylophenone with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazoline (step b). The pyrazoline can then be reacted with arylsulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux to yield the corresponding pyrazole-1-carboximidothioic acid methyl ester (step c). The nitro group can be reduced using sodium dithionite in aqueous basic solution to produce the aniline compound (step d). Acylation of the aniline with ethyl malonyl chloride in the presence of base should produce the amide (step e). Treatment of the amidoester with amines such as methylamine or anhydrous ammonia in a solvent such as methanol or methylene chloride at zero degrees to room temperature should afford the pyrazole-1-carboxamidines with the terminal carboxamido group (step f). Alternatively, the aniline compound can be treated with methanesulfonyl chloride to give the sulfonamide (step g), which upon exposure to an aqueous solution of methylamine and methylene chloride at room temperature should afford the pyrazoline-1-carboxamidines (step h).

Scheme 8 illustrates how treatment of 4′-cyano-2-phenylacrylophenone with hydrazine hydrate in ethanol will produce the 3,4-diarylpyrazoline (step a). The pyrazoline can then be reacted with tri-n-butyltin azide, conveniently prepared in situ by the reaction of one equivalent of sodium azide and one equivalent of tri-n-butyltin chloride (see J. Med. Chem. 1991, 56, 2395), in reluxing toluene or xylene to afford the tri-n-butyltin-tetrazole adduct (step b). The tri-n-butyltin-adduct can be converted to the trityl-tetrazole adduct by treatment with one equivalent of aqueous sodium hydroxide solution and one equivalent of trityl chloride at room temperature (step c). Reaction of this adduct with arylsulfonyldithioimidocarbonic acid methyl esters in a solvent like acetonitrile in the presence of triethylamine at reflux should yield the pyrazole-1-carboximidothioic acid methyl ester (step d). Treatment of the iminothioether with aqueous methylamine and methylene chloride at room temperature should afford the pyrazole-1-carboxamidines (step e). Removal of the trityl group with aqueous TFA in THF at room temperature should yield the unprotected tetrazole (step f).

Scheme 9 shows how to convert 2′-, 3′-, or 4′-polyethoxylated analogs of 2-phenylacetophenones, prepared from commercially available 2′-, 3′- or 4′-methoxy-2-phenylacetophenones via O-demethylation using HBr/HOAc or BBr₃/CH₂Cl₂ and alkylation of the resultant phenols with alkyl-capped or TBDMS-capped halides prepared as described in Nuclear Medicine and Biology, 32, 799 (2005). Treatment of these polyether ketones in 37% aqueous formaldehyde containing piperidine under reflux should give the corresponding acrylophenones (step a). Treatment of the acrylophenones with hydrazine hydrate in ethanol can produce the 3,4-diarylpyrazolines (step b). The diarylpyrazolines can be further treated with arylsulfonyldithioimidocarbonic acid methyl esters, prepared from the corresponding aryl sulfonamides, CS₂ and MeI (see J. Med. Chem., 47, 627 (2004); Chem. Ber. 1966, 99, 2885), in a solvent (e.g., acetonitrile) in the presence of triethylamine at reflux to yield the pyrazole-1-carboximidothioic acid methyl ester (step c). Further exposure of these iminothioethers to an aqueous solution of methylamine and methylene chloride at room temperature should afford the pyrazoline-1-carboxamidines (step d). Removal of the TBDMS-capping group using anhydrous tetrabutylammonium fluoride in THF should produce the hydroxyl-PEG analog (step e).
